Specification of Letters Patent.

Patented Aug. 31, 1909.

To all whom it may concern:

Be it known that .1, JOHN G. HODGSON, a

citizen of the United States, residing in Maywood, in the county of Cookand State of Illinois, have invented a new and useful Improvement in CanCoating or Lacquering Machines, of which the following is aspecification.

My invention relates to improvements in machines for lining or coatingcans on the inside with liquid lacquer or other protective coating.

The object of my invention is to provide, a simple, efficient anddurable machine for automatically, rapidly and cheaply lining or coatingsheet metal preserving cans on the inside, uniformly, perfectly andcontinuously throughout thelr entire interior surface with a protectivecoating of lacquer or other material, and by which the liquid lacquer orother coating material may be applied in exact uniform and measuredquantities to. each can, and by which the lacquer or other protectivecoating applied to the cans may be quickly made dry, hard, solid andfirmly adherent, and also innocuous, tasteless and insoluble invegetable or food acids or juices, and by which the protective coatingmay also be rendered capable of successfully withstanding withoutinjury, the heat of the cooking or processing step to which the cans aresubjected after being filled, and also the heat of the solderingoperation incident to soldering in place the caps that close the fillingopenings in the cans.

My invention consists in the machine or mechanism I have devised forpractically accomplishing this object or result, the same comprisingprimarily a holder for the cans, a spray head adapted to enter the canat one end either by moving the spray head toward the can or the cantoward the spray head, a feed plunger for delivering the liquid lacquerin measured quantities to the spray head as required for coating eachcan, means for imparting relative rotary movement to the spray head orcan, preferably to the can,

' mechanism for inserting the spray head in the can either by moving thespray head toward the can or the can toward the spray head, preferablyby moving the spray head toward the can, a runway or device fordelivering the cans to the can holder or holders, a discharge runway forthe freshly coated cans, and a gas jet or ignition device for ignitingthe vapors in and issuing from the freshly coated cans as they movealong the runway, and-thus flashing and sterilizing the interior of thecans and simultaneously drying, hardening and rendering firmly adherentthe liquid lacquer or other protecting coating applied to the interiorsurface of the can.

My invention further consists in the novel construction of parts anddevices and in the novel combinatlons of parts and devices herein shownor described.

In the accompanying drawing forming a part of this specification, Figure1 is a side elevation of a machine embodying my invention. Fig. 2 is acentral vertical section on line 2-2 of Fig. 1. Fig. 3 is a detailsection on line 33 of Fig. 2. Fig. 4 is a partial detail section on line4-4 of Fig. 2. Fig. 5 is an elevation"partl-y in central verticalsection of one of the reciprocating spray heads and its connectingmechanism. Fig. 6 is a detail horizontal section on line 6- 6 of Fig. 5.Fig. 7 is a detail section on line 7-7 of Fig. 5. Fig. 8 is a detailplan view, partly in horizontal section, of one of the spray heads andshowing the can in seclfion. Fig. 9 is a section on line 99 of in thedrawing, A represents the frame of the machine, B the spray head, G thecan holders, D the carrier or conveyer upon which the can holders aremounted, E the can feed runway or device for delivering the cans to thecan holders, F the can rotating device, G the feed device for the liquidlacquer or coating material, H the discharge runway for the freshlycoated cans, K a gas jet or flashing device for igniting the inflammablevapors arising from and issuing from the freshly coated cans, H anendless belt or device for rolling the cans along the discharge runwaypast the igniting device, M N upper and lower tanks for containing andsupplying the liquid lacquer or coating material to the feed lunger ordevice.

.The spray head B is preferably a looped pipe of substantiallyrectangular form surrounding the compressed air head B which constitutespart of the spray head. The spray head B is preferably furnished with aplurality of upwardly rojecting nipples or nozzles b, the upper endg ofwhich project slightly above the upper surface of the spray or end .13of the can.

head B, and the lower ends of which extend to near the bottom of thespray head'chamher, so that these nipples or nozzles may withdrawsubstantially all the lacquer or protective coating from the spray headB, The compressed air head,'B is furnished with a series of jet orificesY3 through which, blasts of compressed air are directed over the .upperend of the jet nipples. or nozzles 11 of the spray head.

The spray head B is removably secured to the spray head holder B whichis adjustably secured by a clamp screw b on the reciprocating slide B bywhich the spray head is moved in and out ofthe can X m in the head -hespray head liolder B is furnished with'a feed chamber b for the feedplunger G and a further chamber b for the compressing plunger B by whichthe charge 0 liquid lacquer or coating material is forced into the sprayhead, and with a further chamber b for the compressed airplunger B bywhich the admission of compressed air to the compressed air head B iscontrolled.

The feed plunger G is furnished with a feed pocket 9 of a size orcapacity to deliver at each stroke of the feed plunger just enough hquidlacquer or other coating for one can, and the stroke of the compressingplunger is also regulated so as to force just the required charge .ofliquid lacquer or other coating material necessary for one can into eachcan.

The plungers G, B and B are automaticthrough the filling openin 'allyreciprocated as required by means of cams B B B on the rock shaft 13which is mounted on the slide B and which cams operate said plungersthrough suitable connecting levers B B B which are fulcrumed on the barB carried by the slide B The liquid lacquer or coating material feedsdown by gravity from the supplemental supply tank N into the feedchamber b and feed plunger pocket 9 through the connecting pipe 63 Thespray head holder B is also provided with a vent pipe I) to prevent airor other fluid being trapped in .the end of the feed plunger chamber 1).The spray head holder B is further provided with a passage b leadingfrom the feed chamber 12 to the compressing chamber I), through whichpassage the charge of liquid lacquer or coating material in the pocket bof the feed plunger G flows down in front of the compressing plunger Bby which it is forced into the spray head. The compressed air chamber orcylinder 6 of the spray head holder B is connected b a pipe I) with thecompressed air head the pipe b being preferably made integralconstruction adapted to hold the can in cooperative relation with thespray head whether the can or the spray head he the member that isrotated. In that embodiment of my invention wherein the can\is themember rotated, as illustrated in the drawing, the can holder isrotatable or of a construction adapted to permit the rotation of thecan. The construction of the rotatable can holder 0 which I prefer toemploy consists of a pair of rollers, each preferably furnished movablecarrier D, consisting plreferably of a pair of wheels or disks secure tothe shaft D The carrier disks D D may be adjusted farther apart orcloser together on their shaft D as required to accommodate cans ofdifferent lengths, by means of set screws (1.

The shafts (J of the can holder rollers C are journaled in suitableholes or bearings (Z in the carrier disks D D. The carrier D may beintermittently rotated to bring the several can holders thereonsuccessively into re istry with the spray head B by any su1tab emechanism, the same consisting preferably of a Geneva stop mechanismcomprising a radially slotted wheel (1 on the carrier shaft D havingcurved stop faces (1 and which wheel engages a cooperating rotating diskand crank pin 61* (l on the cam shaft P.

The carrier D is preferably furnished with radially projectin arms Dbetween adjacent can holder ro lers to retain the cans in positionbetween adjacent rollers as the carrier wheel or turret D revolves onits own axis.

The device E for delivering the cans to the can holders automaticallypreferably consists of an inclined runway having guide flanges E and anupper guard rail E Any suitable means may be employed for rotating thecan when it is brought into coiiperative relation with the spray head.Instead, however, of rotating or driving the can holder rollers C C inorder to impart rotary movements to the can, I prefer to combine withthe other parts a can rotating mechanism which enga es the can itself,as i are journaled in vertically adjustable beara pulley f which'givesmotion through abelt f to pulley-P on the'shaft' P.

The-liquid lacquer or coating material supply tank M- is" preferablyatight or hermetically closed tank, and it'is furnished with afeed pipem',' th'e lower end an? of whichproj ects inte the supplemental open 1tank N above the lower'end m of the air or vent'pip'e m which leads fromthe upper portion of the closed tank M into the open or supplementaltank N. The lower end m of the vent pipe m thus automatically con trols;regulates 'or"- keeps uniform the height orlevel of the liquidlacqu'eror'coating materlal in the open or supplemental tank- N. When' theliquid lacquer or coating material rises" in the" open" orsupplementaltank N I high-enoughdo'sea-l the lower-end m ofthe vent pipe m furtherflow 'otthe'liquid from the=closed tank Minto the op'entank'N isautomatically stopped'untl'l-the level ofthe' liquid -in the open tank Nagain falls below the lower end 'm of 'th'e vent-pipe m The dischargedevice H by whichthe freshlyi'coatd cans are discharged from the canholders and conveyed past-the gas et or' igniting device K preferablyconsists of a--runway, theinner-end of which is preferablysom-ewhatinclined- The rails of-this runway have-upright flanges h toguide the"- cans as they-roll along it. To insure proper movement of thecans along the runway, I.

prefer-to provide it-with an endless conveyer chain or belt H mounted onpulleys H, theshatf-ts H of which are journaled in suitable hearings orsupports on the frame of the machine.
